Time zone

Time zone
Based on Coordinated Universal Time (UTC), the standard time commonly used is adopted by
countries and regions around the world. The standard time is determined by each country or
region, and the region where the same standard time is adopted is referred to as the time zone,
and presently, the time zone is divided into 40 zones as of March 2015.
DST (Daylight Saving Time)
Depending on the area, DST (Daylight Saving Time) is individually set.
Daylight Saving Time, or summer time, is a system to lengthen daylight time by advancing 1
hour when daylight time is longer during summer. Daylight saving time has been adopted in
about 80 countries, mainly in Europe and North America. The adoption and duration of daylight
saving time varies depending on the country.
 Daylight Saving Time is subject to change due to circumstances of the country or region.
Coordinated Universal Time (UTC)
UTC is the universal standard time coordinated through an international agreement. UTC is the
primary time standard for recording time around the world. The time obtained by adding a leap
second to the "International Atomic Time (TAI)" is determined based on the atomic clock around
the world. It is coordinated in order to compensate for deviations from universal time (UT)
which is astronomically determined by the UTC.
